On the Olympic complex, in cement or, aluminum plants, in harbour facilities,

hospitals, undergrounds and in many other buildings and industrial companies of

the Chinese metropolis Peking as well as everywhere in China, 700.000 kVAr of

compensation power with a detuned reactor of 5.67% or 7% from SYSTEM ELECTRIC

leads to reduced electricity costs, an unloading of the electrical network and an

improved voltage quality.

In the oil refinery of MAZEIKIU NAFTA, an enterprise of ORLEN

GROUP in Lithuania, 63 units from SYSTEM ELECTRIC with a

total power of 23, 400 kVAr ensure an optimized power

factor and unload the power system.

At the German finance metropolis Frankfurt, the load caused by the 5th harmonic

is especially high. More than 400 units from SYSTEM ELECTRIC with a 5.67% or 7%

detuned reactor reduce the energy costs for many customers and improve the

voltage quality in the Frankfurt region.


The airport of Zurich in Switzerland is compensated with 51 units of SYSTEM

ELECTRIC. The 7% detuned reactor systems with a total power of more than

7000 kVAr have been in operation for many years without any disturbances so far.

Also the Swiss Federal Railroad and many industrial companies, for example Swiss

Stahl AG, trust in equipment from SYSTEM ELECTRIC.

More than 350 000 kVAr of installed power testify to the confidence shown by Swiss

companies.

Two automatically regulated filter units of 1500 kVAr each, 690 V, 60 Hz, 5%

detuned reactor, consisting of an 2500 incoming feeder and three control

cabinets with 5 capacitor switching modules of 2 x 50 kVAr each, with overload

switch and freely adaptable number of steps as well as step power. All devices

were equipped with a large back-up in line with SYSTEM ELECTRIC’s security

philosophy. Special importance was attributed to the air cooling system and the

temperature control. The units operate to full customer satisfaction. In the

meantime, other drilling platforms have been equipped with filter units from

SYSTEM ELECTRIC.


A 5.67 or 8.3% detuned reactor power factor correction system, which can be

operated with 400 V / 50 Hz or 450 V / 60 Hz. The unit with a total power of

1200 kVAr is controlled in 24 steps. 600 kVAr are dynamically operated with a

thyristor switch, the remaining 600 kVAr are operated conventionally using a

contactor.

In order to cope with the special system and load conditions as well as the

operation through 2 voltage and 2 frequency ranges a special software was

developed for the reactive power controller.

The company ESD-Sic b.v. in the Netherlands is one of the leading manufacturers

of silicon carbide. During the production process, a mixture of pure quartz sand

and petroleum coke is heated under a plastic tarpaulin to a temperature of

approximately 2300° C by supplying electric energy with a rated voltage of 500 -

600 V, 50 Hz. Both source materials react to silicon carbide. The reactive power

load of the process is 7000 - 8000 kVAr.

A 700 kVAr oven capacitor bank from SYSTEM ELECTRIC. Ten of these units are

necessary per process line to keep the energy and production costs within

reasonable limits. The capacitors are self-healing and environment-friendly.
